Nanite and tessellation in UE5 - Smooth displacement on landscapes

hallatore · March 23, 2024, 6:01am

How to enable Nanite tessellation

Open <project_folder>/Config/DefaultEngine.ini
Add the following under [/Script/Engine.RendererSettings]
- r.Nanite.AllowTessellation=1
- r.Nanite.Tessellation=1

Landscape example

On your landscape in editor, check Enable Nanite (Note: If you do major changes you need to hit Rebuild next to this checkbox from time to time)
In your landscape material, check Enable tessellation
In your landscape material, hook up the Displacement node to your displacement texture sample.

Remove tessellation artifacts/Smooth the displacement

Note: This will hopefully be fixed/improved in a later version of UE5.

If you have enabled displacement you can often see artifacts when close to the material. To avoid this we can smooth out the displacement sampling.

Before:

After:

Make a material function called MF_BlurTextureSample
Make sure Expose to library is checked
Paste the following code

The function takes a TexureObject and not a TextureSample. As long as a TextureObject parameter has the same name as the TextureSample then this works fine.

Hello !

Thanks for sharing this, im having a few issues with this since, probably because im new to UE.

I am experiencing some issues trying to get this to work.


Error: [SM6] /Engine/Generated/Material.ush:3337:8: error: use of undeclared identifier 'Begin'
    return Begin Object Class=/Script/UnrealEd.MaterialGraphNode Name="MaterialGraphNode_0" ExportPath="/Script/UnrealEd.MaterialGraphNode'/Engine/Transient.Material_1:MaterialGraph_0.MaterialGraphNode_0'"
           ^
MaterialEditorStats: Error: [SM6] /Engine/Generated/Material.ush:3337:14: error: unknown type name 'Object'
    return Begin Object Class=/Script/UnrealEd.MaterialGraphNode Name="MaterialGraphNode_0" ExportPath="/Script/UnrealEd.MaterialGraphNode'/Engine/Transient.Material_1:MaterialGraph_0.MaterialGraphNode_0'"

After editing the customcode, giving it 2 input parameters (object and begin) and also hooking up a textureobject and coord it still gives me an error. Could you/someone maybe please give a detailed explanation on how to make this work (especially the custom material function call, a screenshot is welcome)

I would really appreciate the extra explanation as a newcomer!

Thanks in advance and have a nice day.

You can copy & paste the code above directly into you material. It should spawn some nodes.
Then just hook UV and Tex up.

Thanks it worked ! It looks so much better.

Cheers!
